This is the Cycle Electric CE-22A Alternator Kit. The sticker on the box says it fits all 1970-98 Big Twins. It contains a Cycle Electric CE-8188A stator, a Harley-Davidson Motorcycles 29957-81B rotor kit, a Cycle Electric CE-204 rectifying regulator, installation hardware, and installation instructions. When I purchased this kit, the outer box and the box containg the stator had been opened. The rotor is still sealed in the box, and the rectifying regulator is still sealed in plastic. There is clear tape on the front of the main installation instructions. I didn't use this kit. Please ensure these are the parts you need before purchasing.
